Description

The present invention relates to an image processing device, an image forming device, an image processing method, and a program.

2. Description of the Related Art Conventionally, printed matter has generally been cut by stacking printed sheets to form a bundle of sheets, and then cutting the bundle of sheets together (see Patent Document 1). In Patent Document 1, in an image forming apparatus that prints two original pages on the same side of one sheet of paper, the printed paper is cut at the center and the paper is cut under the cut paper stack including the first page. A so-called skewer imposition method has been proposed, in which aggregate printing is performed so that the pages are in the order when stacking the other stack of sheets after cutting.

2. Description of the Related Art In recent years, devices have been used that cut each printed sheet into two pieces in-line (on a conveyance path within the device). With this device, for example, a sheet of SRA3 size (a size slightly larger than A3) can be cut on all sides and in the center to make two sheets of A4 size. By cutting in-line, it is possible to reduce costs by using large-sized paper, and to print without borders at any output size.

Japanese Patent Application Publication No. 2002-281278

(Summary of functions of image processing device)
Next, an overview of the functions of the image processing device 20 will be explained.
The CPU 21 of the image processing device 20 acquires a print job associated with at least document data from the computer 10 via the NIC 24 . That is, the CPU 21 functions as a job acquisition unit.

FIG. 6 shows the data structure of a print job. The print job includes document data, document size settings, sheet orientation settings, cutting settings, binding settings, staple/punch settings, and the like.
The manuscript data may include the image data itself corresponding to the manuscript, or may be identification information (such as a URL) for specifying the manuscript data. FIG. 7 is an image diagram of the manuscript data. In the manuscript data, the i-th page is referred to as the "i-th page."
The document size setting is information indicating the size of the document (for example, A4 size, etc.).
The sheet orientation setting is information indicating the orientation of the sheet, and includes portrait (vertical orientation) and landscape (landscape orientation). In portrait mode, the rectangular area is oriented vertically, as shown in FIG. 8(a). As shown in FIG. 8(b), the landscape is oriented such that the rectangular area is horizontally elongated. The sheet orientation is the orientation of the image in the final output product (in the case where cutting processing is performed, the sheet after cutting).

The cutting settings include at least information as to whether or not to cut the sheet into two.
The binding setting is information indicating the binding direction, and can be selected from left binding, right binding, and top binding. As shown in FIG. 9A, left binding is a binding method in which the left end of the sheet is bound, and pages are turned from right to left. As shown in FIG. 9B, right binding is a binding method in which the right end of the sheet is bound, and pages are turned from left to right. As shown in FIG. 9C, top binding is a binding method in which the upper ends of the sheets are bound, and the pages are turned from the bottom to the top. Binding settings are realized by different rotation angles of images on the front and back sides of the printout.
The staple punch settings include the position of the staple punch (left, right, top) and the number of staple punches (1 point, 2 points, 4 points, etc.).

The CPU 21 executes RIP processing based on the document data and generates bitmap data.
The CPU 21 performs imposition processing based on document data, document size settings, sheet orientation settings, cutting settings, binding settings, staple/punch settings, and the like. That is, the CPU 21 functions as an imposition control section.

Specifically, in printing related to a print job in which manuscript data including eight or more pages is associated, the CPU 21 prints the fourth page and the second page on the first side of the first sheet in that order. Later, the first page is printed on the second side of the first sheet, then the third page, and after the first sheet is printed, the eighth page and then the sixth page are printed on the first side of the second sheet. After that, an imposition process is performed so that the fifth page and the seventh page are printed in this order on the second side of the second sheet. In printing related to a print job, the j-th sheet is referred to as the "j-th sheet."

FIG. 10 shows the printing order of each page determined in the imposition process.
The first surface of the first sheet (the surface that becomes the back surface (top surface) after passing through the second reversing mechanism 35 after cutting) is printed in the order from the fourth page to the second page.
The second surface of the first sheet (the surface that becomes the front surface (lower surface) after passing through the second reversing mechanism 35 after cutting) is printed in the order of the first page to the third page.
The first side of the second sheet (the side that becomes the back side after passing through the second reversing mechanism 35 after cutting) is printed in the order of pages 8 to 6.
The second surface of the second sheet (the surface that becomes the front surface after passing through the second reversing mechanism 35 after cutting) is printed in the order of pages 5 to 7.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the downstream side in the transport direction at the timing when the image forming unit 32 prints. Then, each of the first page, third page, fifth page, and seventh page is rotated independently.
Note that this image rotation control is not performed when the side of the image corresponding to the staple setting or punch setting coincides with the conveyance direction.

FIGS. 11A to 11E show examples of staple positions and examples of "corners or sides of the image corresponding to the staple settings" in each case.
As shown in FIG. 11A, when the stapling position is set to the "left corner", the corner A1 becomes the "corner of the image corresponding to the stapling setting".
As shown in FIG. 11(b), when the stapling position is set to the "right corner", the corner A2 becomes the "corner of the image corresponding to the stapling setting".
As shown in FIG. 11C, when the stapling position is set to "two points on the left", side B1 becomes "the side of the image corresponding to the stapling setting".
As shown in FIG. 11(d), when the stapling position is set to "two points on the right", side B2 becomes "the side of the image corresponding to the stapling setting".
As shown in FIG. 11E, when the stapling position is set to "upper two points", side B3 becomes "the side of the image corresponding to the stapling setting".

FIGS. 12A to 12C show examples of punch positions and examples of "image sides corresponding to punch settings" in each case.
As shown in FIG. 12A, when the punch position is set to "left punch", side B11 becomes "the side of the image corresponding to the punch setting".
As shown in FIG. 12(b), when the punch position is set to "right punch", side B12 becomes "the side of the image corresponding to the punch setting".
As shown in FIG. 12(c), when the punch position is set to "upper punch", side B13 becomes "the side of the image corresponding to the punch setting".

FIG. 13 shows an example of image rotation control on odd-numbered pages. The rotation angle of the image is determined so that the long sides C1 to C4 of the two sides constituting the "corner of the image corresponding to the staple setting" are on the downstream side in the conveyance direction at the timing of printing.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the upstream side in the conveyance direction at the timing when the image forming unit 32 prints. Then, each of the second page, fourth page, sixth page, and eighth page is rotated independently.
Note that this image rotation control is not performed when the side of the image corresponding to the staple setting or punch setting coincides with the conveyance direction.

FIG. 14 shows an example of image rotation control for even-numbered pages. The rotation angle of the image is determined so that the long sides C11 to C14 of the two sides constituting the "corner of the image corresponding to the staple setting" are on the upstream side in the conveyance direction at the timing of printing.

When the print job includes binding settings (left binding, right binding, top binding), when the side corresponding to the binding setting coincides with the conveyance direction, the CPU 21 performs the following operations at the timing of printing by the image forming unit 32: The images of the 2nd, 4th, and 6th pages are oriented 180 degrees with respect to the images of the 1st, 3rd, 5th, and 7th pages (the pages that are finally output as the front page). page and the eighth page (the page that is finally ejected as the back side) are independently rotated.

FIGS. 15A to 15H show examples of image rotation control when a print job includes binding settings.

As shown in FIGS. 15(g) and (h), when the sheet orientation is "landscape" and the binding direction is "top binding", the upper sides D7 and D8 of the image on the first page are " The side that corresponds to the binding setting.

As shown in FIGS. 15(a), (b), (g), and (h), if the sides D1, D2, D7, and D8 corresponding to the binding settings do not match the conveyance direction, the images of even pages Make the orientation the same as the images on odd-numbered pages.
As shown in FIGS. 15(c), (d), (e), and (f), when the sides D3, D4, D5, and D6 corresponding to the binding settings match the conveyance direction, images of even pages are Rotate the images of odd pages by 180 degrees.

Generalizing the above process, in printing related to a print job, the CPU 21 prints the sheet after the 4nth page (n is a natural number) and the (4n-2)th page are printed on the first side of the sheet in this order. Imposition processing is performed so that the (4n-3)th page and the (4n-1)th page are printed in this order on the second side. In this case, the print job only needs to be associated with document data including five or more pages.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the downstream side in the transport direction at the timing when the image forming unit 32 prints. Then, the (4n-3)th page and the (4n-1)th page are each rotated independently.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the upstream side in the conveyance direction at the timing when the image forming unit 32 prints. Then, the (4n-2)th page and the 4nth page are each rotated independently.

When the print job includes binding settings and the side corresponding to the binding settings coincides with the conveyance direction, the CPU 21 prints the (4n-3)th page and the (4n-3)th page at the timing of printing by the image forming unit 32. 4n-1) The (4n-2)th page and the 4nth page are each independently rotated so that they are oriented 180 degrees with respect to the image of the page.
According to the generalized imposition method (page printing order and image rotation angle), the imposition process can be performed on the third and subsequent sheets in the same manner as on the first and second sheets.

The CPU 21 outputs the imposition-processed print data (bitmap data) to the image forming apparatus 30 via the DATA I/F 25.

(Operation of image forming system)
Next, the operation of the image forming system 100 will be explained.
First, in the computer 10, various settings are performed in response to user operations, and print job data is generated.
16 and 17 show examples of a layout setting screen 161 and a finishing setting screen 162 displayed on the display unit 16 of the computer 10.

As shown in FIG. 16, the layout setting screen 161 includes a duplex setting area 41, an imposition setting area 42, a binding direction setting area 43, and the like.
The duplex setting area 41 is an area for selecting whether or not to perform duplex printing. When performing double-sided printing, the user checks the checkbox in the double-sided setting area 41. When performing single-sided printing, the user unchecks the checkbox in the double-sided setting area 41.

The imposition setting area 42 is an area for selecting settings related to imposition. As settings for imposition, 2-sheet separation, 2in1, 4in1, etc. can be selected. Two-sheet cutting is a process in which images for two pages are arranged and printed on one side of one sheet, and the printed sheet is cut into two sheets in a direction perpendicular to the conveyance direction in which the sheet is conveyed. .

The binding direction setting area 43 is an area for selecting a binding direction. As the binding direction, left binding, right binding, and top binding can be selected.

As shown in FIG. 17, the finishing setting screen 162 includes a binding direction setting area 51, a staple setting area 52, a punch setting area 53, and the like.
The binding direction setting area 51 is an area for selecting a binding direction. The binding direction may be selected in the binding direction setting area 43 of the layout setting screen 161.

The staple setting area 52 is an area for selecting settings related to stapling. As settings for stapling, left corner, right corner, 2 points on the left, 2 points on the right, 2 points on the top, and off can be selected.

The punch setting area 53 is an area for selecting punch-related settings. As settings for punching, left punch, right punch, top punch, and off can be selected.

The user selects "duplex printing" in the duplex setting area 41 of the layout setting screen 161 and selects "separation into two sheets" in the imposition setting area 42 by operating the operation unit 15 of the computer 10. In addition, the user can input the binding direction, staple position, punch setting area 51, staple setting area 52, and punch setting area 53 of the finishing setting screen 162 by operating the operation unit 15 of the computer 10 as necessary. Select location. The CPU 11 of the computer 10 generates print job data based on various settings.

FIG. 18 is a flowchart showing the first imposition control process executed in the image processing device 20. This process is realized by software processing in cooperation with the CPU 21 and a program stored in the storage unit 23.

When print job data is transmitted from the computer 10 to the image processing device 20, the CPU 21 of the image processing device 20 acquires the print job data via the NIC 24 (step S1).

Next, the CPU 21 determines whether the document data is eight or more pages based on the print job data (step S2).

If the manuscript data is eight or more pages (step S2; YES), the CPU 21 performs rotation angle determination processing for the first to fourth pages (step S3).

Here, the rotation angle determination process will be explained with reference to FIG.
The CPU 21 acquires information on the output sheet (paper type, size, etc.) and sheet conveyance direction from the print job data (step S11).

Next, the CPU 21 identifies a corner or side of the image corresponding to the staple setting/punch setting based on the staple setting/punch setting of the print job data (step S12).

Next, the CPU 21 obtains, for the odd-numbered pages, the rotation angle at which the corner or side identified in step S12 is on the downstream side in the sheet conveyance direction at the timing of printing (step S13). In the case of a corner, the longer side of the two sides constituting the corner is on the downstream side in the sheet conveyance direction.

Next, for the even-numbered pages, the CPU 21 obtains the rotation angle at which the corner or side identified in step S12 is on the upstream side in the sheet conveyance direction at the timing of printing (step S14). In the case of a corner, the longer side of the two sides constituting the corner is on the upstream side in the sheet conveyance direction.

Next, the CPU 21 independently rotates each page at the rotation angle determined in step S13 or step S14 (step S15).
Note that if the print job does not include stapling settings or punch settings, the processes of steps S12 to S15 are not performed.

Next, the CPU 21 obtains the binding side from the binding direction of the binding settings (step S16). Specifically, when the binding direction is "left binding", the binding side is the left side of the images of odd-numbered pages, and the right side of the images of even-numbered pages. When the binding direction is "right binding", the binding side is the right side of the images of odd-numbered pages, and the left side of the images of even-numbered pages. When the binding direction is "top binding", the binding side is the upper side of the image of odd-numbered pages, and the lower side of the image of even-numbered pages.

Next, the CPU 21 determines whether the binding side and the sheet conveyance direction match (step S17). Specifically, when the sheet orientation is “portrait” and the binding side is “the left side of the image” or the “right side of the image”, the binding side and the sheet conveyance direction do not match. When the sheet orientation is "portrait" and the binding side is the "upper side of the image" or the "lower side of the image", the binding side and the sheet conveyance direction match. When the sheet orientation is “landscape” and the binding side is “the left side of the image” or the “right side of the image”, the binding side and the sheet conveyance direction match. If the sheet orientation is "landscape" and the binding side is the "upper side of the image" or the "lower side of the image", the binding side and the sheet conveyance direction do not match.

If the binding side and the sheet conveyance direction match (step S17; YES), the CPU 21 adds 180 degree rotation for each even page (step S18). That is, the CPU 21 independently rotates the image on the back side (even numbered pages) of the final output product so that it is oriented 180 degrees with respect to the image on the front side (odd numbered page).

In step S17, if the binding side and the sheet conveyance direction do not match (step S17; NO), or after step S18, the rotation angle determination process ends.
Note that if the print job does not include binding settings, the processes of steps S16 to S18 are not performed.

Returning to FIG. 18, the CPU 21 prints the fourth page and the second page on the first side of the first sheet in this order, and then prints the first page and the third page on the second side of the first sheet in that order. Imposition processing is performed so that the image is displayed (step S4). At this time, the CPU 21 arranges the images of each page at the rotation angle determined in step S3.

Next, the CPU 21 performs rotation angle determination processing for the fifth to eighth pages (see FIG. 19) (step S5).

Next, the CPU 21 prints the 8th page and the 6th page on the first side of the second sheet in this order, and then prints the 5th page and the 7th page on the second side of the second sheet in that order. Imposition processing is performed as follows (step S6). At this time, the CPU 21 arranges the images of each page at the rotation angle determined in step S5.
Thereafter, the imposition processing is performed in the same manner until the final page.

In step S2, if the manuscript data is less than eight pages (step S2; NO), the CPU 21 performs other processing (page order control that is not covered by the present invention) (step S7).
After step S6 or step S7, the first imposition control process ends.

In the first imposition control process, in step S2, the process moves to step S3 or step S7 depending on whether the manuscript data is 8 pages or more, but in step S2, it is determined that the manuscript data is 5 pages or more. It is also possible to judge whether or not. In this case, if the manuscript data is 5 or more pages, the same processes as steps S3 to S6 are performed up to the pages included in the manuscript data, and if the manuscript data is less than 5 pages, it is sufficient to proceed to step S7. .

The CPU 21 of the image processing device 20 outputs the print data that has been subjected to the imposition process to the image forming device 30 via the DATA I/F 25 .
In the image forming device 30, the image forming unit 32 performs double-sided printing based on print data, the inline cutting unit 34 cuts the sheet into two sheets, and the second reversing mechanism 35 reverses the front and back sides of the cut sheet. . Then, the cut sheet is subjected to post-processing such as stapling and punching by the post-processing section 37 as required, and the cut sheet is discharged to the mounting section 38.

Note that in the case where the side of the image corresponding to the staple setting or punch setting coincides with the sheet transport direction in the sheet conveyed from the inline cutting section 34 to the discharge section 36 of the image forming apparatus 30 (the position of the staple or punch is If the sheet is not on the rear end side), the sheet is rotated before stapling or punching so that the position of the staple or punch is on the rear end side of the sheet.

As explained above, according to the first embodiment, the image processing apparatus 20 has a first After the fourth page and the second page are printed on the first side of the sheet, the first page and the third page are printed on the second side of the first sheet, and after printing the first sheet, Imposition processing is performed so that pages 8 and 6 are printed on the first side of the second sheet in that order, and then pages 5 and 7 are printed on the second side of the second sheet in that order. Since the printed data is output, the desired output can be easily obtained without having to worry about complicated imposition settings. Thereby, in the image forming apparatus 30, the sheets after cutting are stacked in page order.

In addition, when a print job includes staple settings or punch settings, the corner or side of the image corresponding to the staple settings or punch settings is set to be on the downstream side in the conveyance direction at the timing when the image forming unit 32 prints. , since each odd-numbered page is rotated independently, when the front and back sides of a cut sheet are reversed, imposition can be performed so that the stapling position or punch position is on the upstream side in the sheet conveyance direction. can.

In addition, when a print job includes staple settings or punch settings, the corner or side of the image corresponding to the staple settings or punch settings is set to be on the upstream side in the conveyance direction at the timing when the image forming unit 32 prints. , since each even-numbered page is rotated independently, when the front and back sides of the cut sheet are reversed, imposition can be performed so that the stapling position or punch position is on the upstream side in the sheet conveyance direction. can.

In addition, when a print job includes binding settings and the side corresponding to the binding settings matches the conveyance direction, the image forming unit 32 prints the image in a 180 degree orientation with respect to the image of the odd page. Since each even-numbered page is rotated independently so that the binding setting is made, imposition can be performed at a rotation angle suitable for the binding setting.

In this way, the image processing device 20 can uniquely specify a page order suitable for the device characteristics of the inline cutting section 34 (there is a second reversing mechanism 35 including a switchback mechanism).
Furthermore, the image processing device 20 dynamically determines the rotation angle of each page from information on various settings (such as stapling settings, punch settings, binding settings, sheet conveyance direction, etc.) included in the print job data received from the computer 10. However, images can be rotated on a page-by-page basis.

[Second embodiment]
Next, a second embodiment to which the present invention is applied will be described.
Since the image forming system according to the second embodiment has the same configuration as the image forming system 100 shown in the first embodiment, FIGS. Omitted. The configuration and processing characteristic of the second embodiment will be described below.

In the second embodiment, the image forming apparatus 30 does not include the second reversing mechanism 35 that reverses the front and back of the sheet after cutting and discharges the sheet. That is, the sheet cut by the in-line cutting section 34 is conveyed as is to the downstream discharge section 36. Then, the discharge section 36 discharges the cut sheet to the mounting section 38 without turning the sheet upside down.

(Summary of functions of image processing device)
Here, the functions of the image processing device 20 will be explained, focusing on the differences from the first embodiment.
The CPU 21 of the image processing device 20 prints the third page and the first page on the first side of the first sheet in the order of printing for a print job associated with document data including eight or more pages. Later, the second page and then the fourth page are printed on the second side of the first sheet, and after the first sheet is printed, the seventh page and then the fifth page are printed on the first side of the second sheet. After that, an imposition process is performed so that the sixth page and the eighth page are printed in this order on the second side of the second sheet.

The second side of the second sheet (the side that becomes the back side when ejected after cutting) is printed in the order of pages 6 to 8.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the downstream side in the transport direction at the timing when the image forming unit 32 prints. Then, each of the first page, third page, fifth page, and seventh page is rotated independently.
Note that this image rotation control is not performed when the side of the image corresponding to the staple setting or punch setting coincides with the conveyance direction.

As shown in FIGS. 21(g) and (h), when the sheet orientation is "landscape" and the binding direction is "top binding", the upper sides E7 and E8 of the image on the first page are " The side that corresponds to the binding setting.

As shown in FIGS. 21(a), (b), (g), and (h), if the sides E1, E2, E7, and E8 corresponding to the binding settings do not match the conveyance direction, the images of even-numbered pages Make the orientation the same as the images on odd-numbered pages.
As shown in FIGS. 21(c), (d), (e), and (f), when the sides E3, E4, E5, and E6 corresponding to the binding settings match the conveyance direction, images of even pages are Rotate the images of odd pages by 180 degrees.

Generalizing the above processing, the CPU 21 prints the pages printed on the first side of the sheet in the order of the (4n-1)th page (n is a natural number) and the (4n-3)th page in printing related to the print job. Afterwards, an imposition process is performed so that the (4n-2)th page and the 4nth page are printed in this order on the second side of the sheet. In this case, the print job only needs to be associated with document data including five or more pages.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the downstream side in the transport direction at the timing when the image forming unit 32 prints. Then, the (4n-3)th page and the (4n-1)th page are each rotated independently.

When the print job includes staple settings or punch settings, the CPU 21 sets the corner or side of the image corresponding to the staple settings or punch settings to be on the upstream side in the conveyance direction at the timing when the image forming unit 32 prints. Then, the (4n-2)th page and the 4nth page are each rotated independently.

When the print job includes binding settings and the side corresponding to the binding settings coincides with the conveyance direction, the CPU 21 prints the (4n-3)th page and the (4n-3)th page at the timing of printing by the image forming unit 32. 4n-1) The (4n-2)th page and the 4nth page are each independently rotated so that they are oriented 180 degrees with respect to the image of the page.

(Operation of image forming system)
Next, the operation of the image forming system according to the second embodiment will be explained.
FIG. 22 is a flowchart showing the second imposition control process executed in the image processing apparatus 20. This process is realized by software processing in cooperation with the CPU 21 and a program stored in the storage unit 23.

The processing from step S21 to step S23 is the same as the processing from step S1 to step S3 of the first imposition control processing (see FIG. 18), so the description thereof will be omitted.
The rotation angle determination process for the first to fourth pages in step S23 is similar to the rotation angle determination process shown in FIG. 19.

Next, the CPU 21 prints the third page and the first page on the first side of the first sheet in this order, and then prints the second page and the fourth page on the second side of the first sheet in that order. Imposition processing is performed as follows (step S24). At this time, the CPU 21 arranges the images on each page at the rotation angle determined in step S23.

Next, the CPU 21 performs rotation angle determination processing for the fifth to eighth pages (see FIG. 19) (step S25).

Next, the CPU 21 prints the 7th page and the 5th page on the first side of the second sheet in this order, and then prints the 6th page and the 8th page on the second side of the second sheet in that order. Imposition processing is performed as follows (step S26). At this time, the CPU 21 arranges the images of each page at the rotation angle determined in step S25.
Thereafter, the imposition processing is performed in the same manner until the final page.

In step S22, if the manuscript data is less than eight pages (step S22; NO), the CPU 21 performs other processing (page order control that is not subject to the present invention) (step S27).
After step S26 or step S27, the second imposition control process ends.

In the second imposition control process, in step S22, the process moves to step S23 or step S27 depending on whether the manuscript data is 8 pages or more. However, in step S22, it is determined that the manuscript data is 5 pages or more. It is also possible to judge whether or not. In this case, when the manuscript data is 5 pages or more, the same processing as steps S23 to S26 is performed up to the pages included in the manuscript data, and when the manuscript data is less than 5 pages, it is sufficient to proceed to step S27. .

As described above, according to the second embodiment, the image processing apparatus 20 is configured to output the first sheet to the image forming apparatus 30 including the discharge section 36 that discharges the cut sheet without reversing the front and back sides of the cut sheet. The third page and the first page are printed on the first side of the first sheet, and then the second page and the fourth page are printed on the second side of the first sheet, and after the first sheet is printed, the Imposition processing is performed so that pages 7 and 5 are printed on the first side of the second sheet in that order, and then pages 6 and 8 are printed on the second side of the second sheet in that order. Since the printer outputs printed data, it is possible to easily obtain the desired output without having to worry about complicated imposition settings. Thereby, in the image forming apparatus 30, the sheets after cutting are stacked in page order.

In addition, when a print job includes staple settings or punch settings, the corner or side of the image corresponding to the staple settings or punch settings is set to be on the downstream side in the conveyance direction at the timing when the image forming unit 32 prints. Since each of the odd-numbered pages is rotated independently, imposition can be performed so that the stapling position or the punching position is on the upstream side in the conveyance direction of the sheet after cutting.

In addition, when a print job includes staple settings or punch settings, the corner or side of the image corresponding to the staple settings or punch settings is set to be on the upstream side in the conveyance direction at the timing when the image forming unit 32 prints. Since each of the even-numbered pages is rotated independently, imposition can be performed so that the stapling position or the punching position is on the upstream side in the conveyance direction of the sheet after cutting.

In addition, when a print job includes binding settings and the side corresponding to the binding settings matches the conveyance direction, the image forming unit 32 prints the image in a 180 degree orientation with respect to the image of the odd page. Since each even-numbered page is rotated independently so that the binding setting is made, imposition can be performed at a rotation angle suitable for the binding setting.

In this way, the image processing device 20 can uniquely specify the page order suitable for the device characteristics of the inline cutting section 34 (without the second reversing mechanism 35).
Furthermore, the image processing device 20 dynamically determines the rotation angle of each page from information on various settings (such as stapling settings, punch settings, binding settings, sheet conveyance direction, etc.) included in the print job data received from the computer 10. However, images can be rotated on a page-by-page basis.

Note that the descriptions in each of the above embodiments are examples of the image processing apparatus according to the present invention, and the present invention is not limited thereto. The detailed configuration and detailed operation of each part constituting the device can also be changed as appropriate without departing from the spirit of the present invention.

For example, each function for carrying out the present invention may be divided into a plurality of devices, or may be installed in one device. Further, the functions of the image processing device 20 in each of the above embodiments may be provided inside the image forming device 30. That is, the image forming apparatus 30 may execute the first imposition control process (see FIG. 18) or the second imposition control process (see FIG. 22).

The computer-readable medium that stores the program for executing each process is not limited to the above example, and a portable recording medium such as a CD-ROM may also be used. Furthermore, a carrier wave may be used as a medium for providing program data via a communication line.
